BOX-LOOP.

SPCIFICATIQN forming part of Letters Patent No. 271,170, dated January 23, 1883.

.Application filed November 18, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN WATrEas,ofNew York, in the county and State of New York, have invented an Improvement in BOX-Loops, of which the following is a specification.

Figure 1 is a plan or top view ot' my improved boX-loop; Fig. 2, a vertical longitudinal section of the same; Fig. 3, a bottom view of a piece of carriagelcurtaiii, -to which my boxloop is attached; Fig. 4, across-section of the same; Fig. 5, a bottom view of a modification thereof, and Fig. 6 a vertical longitudinal section of said modification.

lhe object of this invention is to produce for practical use a box-loop for carriages or other purposes, that is made entirely of indiarubber or analogous material-that is to say, where the body of the loop is made Without any joint. Leather loops have heretofore been proposed, also metallic loops; but in either case ajoint had to be made along the lengthof the loop, either inform of a seam or as a lap-joint, or otherwise, and Where a box-loop was thus formed of folded material with a joint, the

joint was apt to open under strain, or otherwise, and to thus destroy the entire value of the box-loop. When india-rubber is used for a box-1oop, it can be molded Without any joint whatever on a suitable mandrel and in a suitable mold, and can then be attached to the .fabric in various ways. One manner ot' attaching it to the fabric and of attaching to it the usual end buckle is shown in the drawings; and the present invention consists, first, in the employmentof a seamless box-loop; and, secondly, in the particular manner, herein described, of fastening the same to the fabric and to the buckle-carrying plate.

In the drawings, the letter A represents the rubber loop, the same being formed ofvone continuous piece ofindia-rubber Without any joint or seam. This box'loop A is'open at the ends in the usual manner. Upon its bottom lies a metallic plate, B, which is turned down and under the box-loop at the ends, as shown in Fig. 2, so as to embrace the back pin of the buckle D, forming ajoint on which the buckle can swing. The plate B has two (more or less) prongs, a, formed from it by incisions that cut out the contours of euch prong, leaving them,

however, attached at one end, and directly beneath each prong (while the same is still in the plane oi' the plate B) is cut out of the bottom b of the loop A a piece of a form Vand size corresponding to the form and size ot' the prong,

producing thereby slots c in the bottom of the loop. Through these slot-s c tlllelprongs a can be carried down so that they will project vertically below the box-loop A, and these same prongs can then be passed through slits in the curtain or fabric E, and turned under the same, as shown in Fig. 2, thereby fastening the metal plate B to the bottom of the box-loop, and also fastening the entire box-loop to the curtain or the fabric E, and serving also, by the same means, to hold the buckle l) properly in place.

The modifica-tion which appears in Figs. 5 and 6 consists in substituting for the plate B, that extends throughout the entire length of the loop A, two short plates, B and B2, each having a downwardly-projeeting prong that fastensit to the bottom of the loop and to the curtain; but in this modification the elongated slots c in the bottom of the rubber loop are not needed.

The plate B, as shown in Fig. 2, may be molded onto the bottom of the loop A, if desii-ed, and will not have any projecting part in the way ofthe necessary sections of the mold in which the rubber is formed, for, while being molded onto the bottom of the rubber loop, thc prongs will be at'in the plane ofthe plate B, and are bent downward through the slot c after the rubber loop has been taken outof the mold. The elastic loop, being rectangular on the outer and also on the inner side in crosssection, as shown in Fig. 4, has equal strength throughout, and is for that reason superior to bent loops, which, when bent, are necessarily weakened at the angles. lt also at all times maintains its form, and stillyields to pressure and to the bending of the curtaina property not possessed by loops that might be made of cast metal.

l. lhe rubber box-loop A, provided with means, substantially as described, for attach- 4the purpose set forth.
